Paint & Pigment Processing Solutions

Rotho peristaltic pumps precisely meter and transfer paints, pigments, inks, and coatings - handling abrasive particles, high viscosities, and shear-sensitive formulations with consistent accuracy.

Paint & Pigment Challenges

Paint and coating manufacturing demands precise metering while handling materials that quickly destroy conventional pumps. Abrasive pigments, solvent-sensitive formulations, and the need for exact color matching create unique pumping challenges.

Abrasive Pigments: Titanium dioxide, iron oxides, and metallic particles wear out seals and impellers
Shear Sensitivity: Some coatings change viscosity or color when subjected to high shear
Precision Metering: Color matching requires exact, repeatable dispensing
Chemical Compatibility: Solvents, resins, and reactive components require resistant materials
High Viscosity: Heavy-bodied paints and mastics exceed 50,000 centipoise

Why Rotho for Paint & Pigment

Purpose-built features for coating and pigment applications

Precision Color Dispensing

Linear flow-speed relationship provides exact, repeatable metering for color matching. No slip means predictable output at any speed - critical for batch-to-batch consistency.

Exact volumetric metering
No slip across flow range
Repeatable dispensing
Signal-controlled output

Handles Abrasive Pigments

Reinforced hoses with up to six layers of nylon handle abrasive pigment slurries. The only wear item is the hose - no seals, impellers, or rotors to replace.

6-layer reinforced hoses
Single wear item
No seal degradation
Extended service life

Gentle on Formulations

Low-shear rolling action won't break emulsions or alter thixotropic properties. Ideal for shear-sensitive latex paints, metallic coatings, and specialty finishes.

Preserves viscosity profile
No emulsion breakdown
Maintains gloss levels
Protects metallic flakes

Chemical Resistant

Seven hose materials available to match your chemistry - from water-based latexes to aggressive solvent systems. Quick-change hoses simplify material switches.
